REOEPTACL'E COVER.

Application. filed. June .9,

The present invention relates to receptacle covers and has as itsprimary object to provide improved means for fastening or locking coverson containers, and receptacles of various description.

It is a further object of .the invention to provide improved fasteningor locking means for the cover which will always compel the seating ofthe cover in a predetermined angular relationship on the container.

Other objects will be apparent from the following description taken inconnection with the accompanying drawing, illustrating apreferred-embodiment of my invention.

In the accompanying drawing:

Figure 1 is a vertical sectional view of the can or receptacle takenapproximately on the plane of the line 11 of Figure 2;

Figure 2 is a plan view of the container, and

Figure 3 is a disassembled or exploded view showing the various partsmaking up the improved locking means.

The receptacle is indicated at 5, being representative of any type ofcontainer to which my improved cover is to be applied. As illustrativeof such containers the cover may be applied to all cans, syrupdispensing receptacles and preserving cans, etc. In the oil canembodiment chosen for exemplification a handle 7 is secured to the sideof the can body. The cover is indicated in its entirety at 9, this covercomprising a tapered spout 11 of any desired form.

The cover is formed with a downwardly turned peripheral flange 36 whichengages over an annulus or ring 37 secured to the reduced neck 6 of thecan. This annulus is formed with an inwardly extending flange 38 toprovide an extensive seating area for the gasket 39 confined between thecover and this annulus 37. Formed around the lower edge of the flange 36are a plurality of inclined keys or segments 41 that have lookingco-operation with segments 42 on a looking ring 43. The locking segments42 are turned inwardly and are also sloped to have cam co-operation withthe sloped locking segments 41. These locking surfaces form in effect abayonet joint for locking the cover on the can. The locking ring 43 hasan inwardly turned flange 44 which sits on a ring 45 secured to the canbody. A flange 46 on the lower edge of the annulus 37 over- 1924. SerialNo. 718,712.

lies the flange 44, this flange46 and the ring 45 forming upper andlower seating surfaces for the rotatable locking rings 43. In assembly,the locking ring is first placed on the lower bearing'ring 45, afterwhich the annulus 37 is slipped down over the reduced neck 6 and isWelded or otherwise suitably secured to this neck.

The locking ring 43 may be formed of sheet metal, and has diametricallyopposite lugs 48 extending outwardly from the body of the ring, by whichthe ring can be turned with sufiicient pressure to force the cover 9down firm against the packing ring 39. The

cover 9 may also be formed of sheet metal with its locking segments 41rolled outwardly in the shaping operation. The members 41 are receivablein the openings 40 in assembling the cover on the can.

Where it is desired to compel seating of the cover in a predeterminedangular position on the can or receptacle, a lug 51 is pro ected fromthe side of the annulus-37. A co-operating slot or recess 52 is cutthrough one of the locking segments 41, and through theflange 36, forengaging over this positioning lug 51. The presence of this lug 51obstructs seating of the cover in any other position than in thepredetermined angular position on the container.

In replacing the cover on the can, the locking segments 41 are passedthrough the openings 40 on the locking ring and the slot 52 is broughtinto registration with the lug 51, whereupon rotation of the lockingring 43 will force the cover down against the flange 38 with the coverin its desired angular position.

Having thus described my invention, what I claim is:

1. In combination, an oil can or the like, a cover for said can,inclined locking surfaces on said cover, a locking ring, inclinedlocking surfaces on said ring for engagement with the inclined surfaceson said cover and a lug for compelling seating of said cover in definiteosition on said can.

2. In combination, an oil can or the like,

a cover for said can, locking segments having inclined locking surfacesextending from said cover, a locking ring having cooperating inclinedlocking surfaces for engagement therewith, and lug and slot means forcentering said cover on said can. I

3. In combination, a container, a cover a ring member rotatively mountedon said flange and having inwardly projecting sloped cam members, aretaining ring fixed on said cylindrical lflange to prevent removal ofsaid ring member, and a cover having outwardly extending sloped flangemembers to be received under said cam members to clamp said cover andcan by rotation of said ring member.

5. In an oil can or the like, a container having a handle and anupturned cylindrical flange, a ring member rotatively mounted on saidflange and having outwardly projecting sloped cam members, a retainingring fixed on said cylindrical flange to pre vent removal of said ringmember, a cover having outwardly extending sloped flange members to bereceived under said cam memhere, a curved spout on said cover, and stopmeans between said cover and can determining the rotative location ofthe dischargin end O'l': said spout.

In witness whereof, I hereunto subscribe my name this 4th day of June,l92a.
